An Overview of Low Altitude Airways

[@Blackhawkpilot14]

The OROCA that is mentioned at 4:30 IS NOT TO BE USED for RNAV/Direct route flight planning. They are on the chart only as a quick reference for situational awareness, these OROCA are not a "verified" altitude. Excerpt from the Instrument Procedures Handbook: OROCAs are intended primarily as a pilot tool for emergencies and SA. OROCAs depicted on en route charts do not provide the pilot with an acceptable altitude for terrain and obstruction clearance for the purposes of off-route, random RNAV direct flights in either controlled or uncontrolled airspace. The only way to ensure obstacle clearance is to plan your Direct Route on a CURRENT VFR Sectional by clearing 4NM either side of your route and referencing the Chart Supplement and NOTAMS for NAVAID reception, airspace changes and obstructions. remember that the rounding rule on obstacles is 49/50, 49 or less feet round down 50 feet or more round up tp the next 100 foot increment. Additionally RNAV(GPS or VOR/DME) routes MUST avoid all Restricted and Prohibited areas by 3NM.

At 4:51 you state that you must enter and exit at a designated fix. This statement is only partially true in that you seem to mean at a "published fix, not true. You can exit or enter anywhere along an airway by using a "User-Defined Waypoint". If your aircraft is equipped you can designate on your flight plan either a LatLong or Fix/Radial/Distance point to define the route of flight thereby conforming to FAR 91.181. Page 2-32 paragraph "User-Defined Waypoints" of the Instrument Procedures Handbook (FAA-H-8083-16) outlines this procedure. Equipment necessary can be either GPS or VOR/DME since both are considered to give RNAV capability.

FINALLY!!! My question has been answered!

[@dylanshure5418]

what is the number under the Vxxx. for example, V408 on that chart has a 27 under it. what is 27?

[@kurtreber9813]

Distance (between fixes, I think)
